A flowline safety joint having a tubular member supported from a subsea tree structure, an elbow having a horizontal passage therethrough and a vertical passage extending upwardly from said horizontal passage, a stab-in male member having a leading end, a trailing flowline connecting end, a passage therein and terminating short of said leading end and a vertical opening in said male member communicating with said vertical passage through said elbow when installed within said horizontal passage, and a flat surface surrounding the opening of said vertical opening in said male member. A seal providing a metal-to-metal seal between the lower end of the tubular member and the flat surface on said male member, and a swivel member for connecting said elbow to said tubular member, said swivel member including an element increasing the downward loading of said tubular on said seal to control the loading of said male member at which it releases from said horizontal passage through said elbow.

In accordance with certain preferred aspects of the present invention, there is provided tree running tool with a mechanical mechanism for unlatching the tree running tool from a side valve tree. The tree running tool is formed from a tool body, a stem, a telescoping element, a retractable spacer, a means for moving the spacer, and a means for attaching the telescoping element to a lift device. The tool body has an upper end, a lower end, and a longitudinal axis. The stem is fixedly attached to the upper end of the tool body and extends axially therefrom. The stem has a lower end attached to the tool body and a generally annular flange at a position spaced apart from the tool body. The telescoping element is positioned alongside the stem. The telescoping element has a generally annular flange at a position between the generally annular flange of the stem and the tool body. The retractable spacer is movable from an engaged position between the generally annular flange of the stem and the generally annular flange of the telescoping element, in which the spacer spaces the generally annular flange of the stem apart from the generally annular flange of the telescoping element, to a retracted position in which a void is formed between the generally annular flange of the stem and the generally annular flange of the sleeve.

A well completion system for a side valve tree that has a precision cut low profile helix that can be used in completing a wellbore where the bore is substantially curved is provided. The well completion system has a typical spool body assembly having an inside surface defining a vertical bore extending therethrough and having at least a lateral production fluid outlet port. The spool body assembly has a helix is positioned at the lower end. The helix has a tubular member having a generally cylindrical outer surface defining an outer diameter and a generally cylindrical inner surface defining an inner diameter, an upper end and a lower end. The tubular member has an organ pipe-shaped cut in the upper end so that the upper end is generally elliptically shaped to form a pair of arcuate ramps which meet at an apex at the upper end and at a longitudinally extending slot near the lower end and a means for attaching the helix to the spool body assembly. An orientation key on the tubing hanger is precision machined to match the profile of the helix.

A well completion system having a spool tree body defining a vertical bore extending therethrough. The vertical bore defines an annular recess adjacent to the lateral production fluid outlet port in the spool tree body. A tubing hanger is connected to the spool tree body. The tubing hanger defines a vertical production bore extending therethrough and has at least a lateral production fluid flow port. The tubing hanger is positioned within the vertical bore such that the lateral production fluid flow port in the tubing hanger is in flow communication with the lateral production fluid outlet port in the spool tree body. There is a removable plug that seals the vertical production bore extending through the tubing hanger above the lateral production fluid outlet port in the spool tree body. A stopper means seals the vertical bore extending through the spool tree body above the removable plug. A workover port extends laterally through the spool tree body and penetrates into the vertical bore above the stopper means. A tubing annulus fluid flow port extends laterally through the spool tree body from beneath the second sealing means from a tubing annulus. The workover port and the tubing annulus fluid flow port are interconnected via an external loop line containing at least one valve.

A lateral connector for a tube assembly has a modular unit which can be used to establish a lateral connection through the sidewall of a tubular member positioned around it. The modular unit has a carrier ring, a coupling element, and a carrier body. The coupling element can move radially but not axially. The carrier ring has generally cylindrical inside and outside surfaces. The coupling element is carried by the carrier ring. The coupling element has a longitudinal axis which is generally radially positioned with respect to the longitudinal axis of the carrier ring. The coupling element has an inner end and an outer end and the outer end has a sealing face. A carrier body having a generally cylindrical outside surface is positioned coaxially inside the carrier ring. The cylindrical outside surface of the carrier body is adjacent to the cylindrical inside surface of the carrier ring. A wedge positioned within a slot and grove arrangement is used to radially move the coupling element in the carrier ring in response to relative longitudinal movement between the carrier ring and the carrier body.

A completion system or tree system for a subsea well having an anchor base on bottom surrounding a well bore, a conductor pipe lining the upper end of the well bore and connecting to the anchor base, a guide base landed on the anchor base and having an upwardly facing funnel positioned in the opening of the anchor base, and a production string extending through the conductor pipe and bending to a substantially horizontal position slightly above the guide base with the start of its gradual bend being below the funnel and with sharp bend production tubing bending immediately avove the funnel since no high profile guide base is present on the anchor base.

An apparatus for use in subsea well completion systems is provided. The apparatus has an isolation sleeve and an extension sleeve. The isolation sleeve has a first end, a second end and a longitudinal axis defined between the first end and the second end. The isolation sleeve has a generally tubular shape. The extension sleeve has a first end attached to the second end of the isolation sleeve to form an assembly comprising the isolation sleeve and the extension sleeve, a second end, and a longitudinal axis that is coaxially aligned with the longitudinal axis of the isolation sleeve. Like the isolation sleeve, the extension sleeve has a generally tubular shape.
